We move here in December 2011. We are used to walking around our yard bare footed. Not with these things, they hurt going in and coming out. I have 2 questions. How do I get rid of them and how do I get rid of them. Don’t care what they are. Thanks, Walter.

Burrweed. You can kill it easily now with a post emregent herbicide containing 24d. If you have centipede or st augustine grass make sure to buy a product safe for use on these turfs. Spray the lawn and wait a week or so for the weeds to start dying. Mow the lawn fairly low when it is dry and use a bagger. This will suck up a lot of the seeds which are the poky part. Low mowing will probably stress the grass but is worth it. Repeat this process if needed, and as suggested use pre-emergent in feb to keep it from coming back.
